Personally, I think you should be able to come back from suicide, but it should take 2 to 3 times longer, and maybe some extra side effects.
But I also think that if your character commits suicide then why would you bother applying for a cloning app? Because if you do want to keep playing that character, why would you commit suicide in the first place? The only exception would be if in a serious situation, someone forces you to kill yourself, to prevent other consequences. But that should be the only exception.
Suicide is usually something you shouldn't do anyways.
